Best way to build with BOTH bcc32 and bcc32c

Using C++ Builder Professional 10.2.1 and DUnitX.

I am writing unit tests to be sure that existing code built with bcc32 runs correctly when built with the clang compilers, bcc32c and bcc64. I will extend the project to include android and ios targets shortly. Right now, my test project includes 32-bit Windows target and 64-bit Windows target. To build for bcc32 and bcc32c, I have to change the project option 'Use classic Borland compiler'. Is there a way to have 2 32-bit Windows targets, one for bcc32 and one for bcc32c? Or maybe there is a better way to meet the need?
