You can create multiple smaller Repeater Regions, around each button in question.
You could also create a larger Repeater Region around all of your buttons.

If you will sometimes want to use this, but not always, you could create an Action Target Group as the recipient of the click and enable KVM mode to block the click in the local window.
Then create a two step mapped key, to add/remove the desired targets from the ATG.
Actions > New Target Group Action > Add/Remove Target from an ATG.
Probably combine this with a Pop Up Text action, for each step to give you visual notification of your state.
