If a Personal Fundraising Champion would like their funds designated to a particular designated fund, it would be nice to have that choice built-in as part of the setup process.

You can have a designee dropdown on the form, but that gives the choice to the donor entirely and not the champion. You could also set up separate donation forms for each designation and separate Personal Fundraising campaigns for each to accomplish this, but if you have several funds (e.g. 200) this isn't super feasible.
