Date Field: How to activate only certain disabled dates?

Hello. I have one date picker. MY activity is only saturday and sundays so I have only enabled this 2 days of the way.

But sometimes I ohave activity in a friday or thursaday. Could I activate only 1 specific friday?

Unfortunately, it is not possible to enable certain dates once you have  disable them, you would need to disable custom dates so this way you could leave only certain dates enabled, you could also disable only certain ranges, this way you could enable or disable only some days. You can get more info about date limits on this guide: How-to-Use-the-Date-Limits-Option

I will also forward this to our second level as  feature request, though we cannot provide an ETA or ensure this can be implemented, we will let you know as soon as we receive any update about it.
