bg checkbox with card specific value?

[Tiemo Hollmann TB]

Hi,

when having a shared bg field, I can put different content into the same
field on each cd with this bg.

When having a button, eg. Checkbox on the same bg, the hilite status of this
button is the same on each cd and can't be set different on each card.

Is there any option where you can share buttons on  a bg in the same kind as
fields?

Thanks

Tiemo
