VS2019 - Debugging without the exact code

In previous versions of VS I could press F5 to start a Debug session and if the code had changed slightly it'd give me the option to rebuild or not rebuild - but VS2019 always rebuilds without giving me any option.

Under Tools->Options->Debugging I disabled the option to Require source files to exactly match the original version but that doesn't seem to help. Is there some other setting that'd allow me to start a Debug session even if a few source files have changed slightly?

Tools->Options->projects and solutons->build and run-> Then choose from comboboxes whether to:
"Prompt to build" / ...
"Prompt to run" / ...

That looks promising Victor - many thanks!
