If you want a standout bio for each artist like the bio that is in the left column of your FAA account, no, it cannot be done. Bios in description area may not be seen.
Using the current FAA capabilities, about the best workaround I can think of is this:
In the bio area on the left, have a title that says Artist Biographies and then a link to a FAA blog page.
This FAA blog page would serve as a table of contents with names and links to individual artists and their bios. These individual bio pages would each be a FAA blog.
Edit: or alternatively, in the left bio column you can list the artists there and the links to the FAA blog articles about each one. In essence, the bio area to the left would be a table of contests. You can embed html links there.
