Header toggle Button

Is there a way to press a header button for a LoveLace card containing multiple buttons? I used to be able to trigger a bunch of firmware updates (for Shelly units) back in the days they appeared as switches by hitting the header switch in the LoveLace frontend. That is impossible now that they are buttons without a ‘state’. Is it possible to activate a ‘Header Toggle’ (as button press in stead of header switch) if a card contains only a bunch of buttons? (in my use case over 100…)

show_header_toggle: true

That works indeed for a list of switches, it creates a "master switch’ together with the title of the card. However, it does not work with a list of button entities. No ‘master button’ showing with the title. That was what I suggested.
