Drive the checkmark of a date field in a data card

Hi all

The SolidWorks PDM Data Map Editor provides a date field that has a checkbox on the left...

I found a use for it but problem: I can't find how to drive it! Is this even possible?

Any ideas? Experience on the subject?

Thank you in advance for the help you can give me.

If you look quickly, this box must be linked to a variable and fill in the box corresponding to this variable once the box is checked.

For example, I linked it to the creation date and when I check the box, the creation date box is filled in the data card:
