PRSice-2 without Ref SNP ID

Does PRSice-2 support a base tile that has chromosome number/name and chromosome position instead of reference SNP ID in the base file?

I’m trying to calculate PRS scores using a weights file from the PGS catalog with ~6 million variants. The file has only chr name and chr positions. Does PRSice-2 support such files as base files? Or, is there a way to get the ref SNP ID in bulk for all the ~6 million variants using the chr name and chr positions?
