[O] Use properties in clocktable header?

[Ken Mankoff]

Hello,

I'd like to compute Org clock-tables for a time range, and rather than 
hard-coding :tstart 2025-01-01 :tend 2025-01-31, I'd like to specify these in 
the section PROPERTY drawer. This lets me access these in a {{{macro}}} and use 
them elsewhere on an invoice. Is this possible?

Thanks,

  -k.
