QRC: extraction fails due to ports names including the "+" character

Hi! The QRC extraction of various cells is failing due to them having port names that use the "+" character. For example, In the QRC log file I get:

+ERROR (LBMISC-215479): at "agds2rcx": syntax error in file /path/to/my/svdb/my_cellname.ports because of an invalid character '+' at line 12

(and in the my_cellname.ports file I see that line corresponds to the entry associated to a port named "clock_latch_N+1").

Is is possible to make PVS/QRC support these port names with the "+" character? We have many cells affected by this, so we'd like to avoid the pain/risk of changing them now (tapeout time).

Thanks and regards, Jorge.
