Use block as form datasource?

Have a form on a page that the public can use to select a date to sign up for a meeting.  I would like editors to be able to create a list of dates that the form can use and have dates fall off the select list as the meeting approaches or we reach a limit that is set.  Could I create a block that contains a list of dates to use as the datasource for the list items in the form?  I'm inclined to say yes, but new to Episerver.  Completed a few of the online courses that have been offered...  Time to test my knowledge.

Thanks,

Tim
