Is there a way to make a paragraph style to begin with a custom bullet plus numbering?
I've tried use numbering with "^B(^#)^t" as number style, but then I can't choose the proper bullet.

Thank you very much.
I think that you may be trying to do more than InDesign's bullet and numbering feature can accomplish by itself. There are a few hacks I can think of, but no way to do what you want with only the bullet & numbering feature.
One way to get what you want would be to use an ordinary numbered list and then insert an anchored object:
