Replacement for WR Build preview?

We are actually replacing the old 4D Write plugin with the new Write pro in a large application based on 4D 16 R6 on Mac.
I don’t see actually a way to replace the old command WR Build preview.
As solution I print the new Write pro object to PDF using WP PRINT and get the single page I want to preview with READ PICTURE FILE.
It works correctly, but the new command WP PRINT is incredible slow.
The old command WR Build preview was working as a charme and much more faster to this new solution am trying to achieve.
Any suggestions from the community ?
Thanks in advance !!
