Is there a way to have a link / button in a grid on the record summary page that can trigger a related action on the same record?

I will say my concern here, if you find a way to do it, is that if the RAs have visibiity rules that have to be evaluated on top of any record filters, etc that is going to make the record summary take a long time to load.
If you can figure out a way to give the experience, might want to look into a Report instead.

Some features to look at a!startprocess, decison designer (can result in a process), grids, et

Thanks Christine. I got your concern. In our case, we do not have many visibility rules for the related action view - visibility is controlled at group level - and also most of the related actions will be open if the user has access to this record.
Re: startProcess, I think it triggers the process in async mode. In our case, user wants to click on the related action and continue with the next process (as usually done from the related action view) - so that may not work. Can you please advise if there is any other alternative? Really appreciate your time and inputs.

Does this approach have enough similarities to what you are trying to do to give you some ideas to play with:
