Hi,
Using a 3rd party preset of Filmpack (or a custom made preset of FP) within Photolab is not possible.
See: Any way to reuse FP preset in PhotoLab? - #8 by sgospodarenko
The only way to do this is to make a simular preset yourself within Photolab, based on the same adjustments of the 3rd party or custom preset of FP.
Kind regards,
Lex
