We have a video to explain our new Option-Click feature coming to MBS FileMaker Plugin for version 11.2:
So Option-Click on the gear icon will let FileMaker open the dialog or show the popover. The MBS Plugin notices the option key is down and then clicks for you the button to open the calculation dialog.
The new MBS FileMaker Plugin 11.2 are coming in May 2021 and include this feature. We may tune it a bit more and if you like to try it, please play with 11.2pr4.
