I don't think, the designers of the Quicken RPM feature had vacation rentals or hotel room reservations by the day, week or month in mind when they wrote the code for "RPM 101" many years ago.
My 2cents' worth: A different software package might be better suited for your purpose, but please don't ask me which one.
I let the local RPM experts answer your specific question. There might be a workaround, but it probably will be awkward.
