I cannot give an answer whether this is something that would be possible in the near future, however what I can do is make the request. It is up to the development team to approve it.
However the issue is on the side of Toolset Forms and the nested shortcodes breaking the expected input.
I have another question : how do I structure my hook to use several queries inside (ie: the idea here is to use the hook for all needed filtering parameters).
The Views is related to products and I have several custom fields to manage :
_stock, wpcf-annule, wpcf-type-evenement and wpcf-annee-univers
All these custom fields belong to product and could be retrieved from the database.

Pat
