I'm making large form fields where the user needs to be able to list out many items while keeping them separate(some combined) so the person collecting the form knows which of the items belong together as a set and which are on their own. I didn't do separate fields for each item because there can be hundreds of items entered at the same time. I think being able to use bullet pts within the field will keep the items separate. Is this possible?
Not really. But you can use an asterisk (*) instead.
If you make the field multiline and allow Richtext formatting, then you can paste in formatted text from a word processor with bulleted lists and they should appear with the same formatting. Don't know if you'd be able to edit the formatting within the PDF other than the simple properties that are accessible via the text style dropdown (i.e. bold/itallic/superscript) but you can paste in formatted text including indents, colored text, paragraph spacing, etc. This should work within Reader as well.
