Can I put a date picker in a Sugar Alert?

I have a custom module where a restricted number of users can select multiple records in list view then choose a list view Action that in turn defines a job in the Scheduler that will execute for each of the chosen records.

When they choose that list view action I would like to prompt them for a run date for the job, I would then set that, and a hard-coded time, as the execute_time for the job.

How can I put a date picker in a confirmation alert? Or is that even possible? Anyone have ideas on how best to do this?

thanks,
