Thanks @michel and @Lievelabels.nl.
I have added option priced patch in last release.
Now I am confused here. Michel has suggested a way where no code need to be changed in PPOM but user have as to make two metas. Whereas Lievelabels.nl has suggested some change in code (PPOM), and I have no issue to add this as long as it helps with WC Bundles.
So now what solution should I adopt? In my opinion Michel solution is little long for user. So better approach that we add some changes in PPOM and it works fine, right?
Looking forward your responses.
