Run a SC based on output of another SC

hi,
feel this is going to be a silly question but not being a real developer but a copy paste warrior I have to ask

I have a pretty complex page that runs quite a few SC queries, many are based on another action, i.e an update/delete action so only triggers the SC when the user does some action on the page.

but, is it possible to have a SC run on page load BUT only when another SC returns a certain value/

i.e I have a page that has a clients booking summary, the booking will get marked as “complete”, so when the page loads we know the job is complete, if that is the case I need to run a SC to see if they have left a review for the booking and if not present them with a box to leave a review.

I know about doing conditional rows/columns so can show my review row when “complete” is true, but, I only want the review SC to run when this panel shows

hope that all makes sense. just trying to minimise the number of connections on page load

thanks
Darren
