Save the CMYK build as a spot color, then you can adjust the CMYK values together using the slider in the color palette.
The thing is that I have exact CMYK breaks that I need to keep so I don't want to convert it to a spot color. Should I convert to a spot temporarily then convert back to CMYK? Or is there a better method?
I would think that would be sufficient...guys?
Why not just enter the values in the fields beside the % signs in the Color palette/panel (Window>Color)?
Thanks for the suggestion Jacob!
However, the color palette only gives me the CMYK break percentages. What I'm looking for is a tint slider where I can type in one percentage number, for example 10%, 30% etc... Does that make sense?

That would be the best solution. It works.
If you are working in specific percentages like the ones you mention, and especially if you need several such tints of the same colour and/or repeated tinting of different colours, you may consider this way:
1) Create a white rectangle (could be 10x10 at 0,0);
2) Object>Transform>Move a copy (could be 100 to the side) and change to full saturation of the colour in question;
3) Select both and Object>Blend>Make (options could be Specified Steps 9);
4) Object>Blend>Expand and Object>Ungroup.
With the values mentioned in () you would now have exact 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100, % tints to pick from.
You could keep copies of 3), and with each Direct select the end coloured square and change to another colour, then just repeat 4). You could also just create a white to white blend first and change colour values in the copies.

When you define the process Swatch, turn on the Global checkbox. Thereafter, you can select that process color, and the Color Palette will show one slider, for percentages of that Global color, which is still CMYK, not spot.
After selecting whatever percentage you want, choose Create New Swatch again. The resulting Swatch will be a tint of the CMYK process swatch. Edit the original Global process color, and you'll see the tint Swatch(es) based upon it update accordingly.
Assuming CS3 or later, select the Global Swatch, open the Color Guide palette. From its flyout menu, turn on Show Tints/Shades. From the flyout menu select Color Guide Options to enter the number of tints you want (ex: 9). The tint percentages will be the color chips with the little triangle in them. ShiftSelect those, then click the Save Color Group To Swatch Panel button (it looks like a folder). You'll then have the original Global Swatch grouped with 9 other swatches which are tints of it, in 10% increments.
