Filter variable products to show only 1 item per variable product

[ChristianAF]

User story

Checking the plugin "Product feed Pro" i found this:

This will add the possibility to not include all variations or only include the parent product or only one variation with the lowest price.

Is your feature request related to a problem?

There are some merchants that were complaining that they have all variable products and feed is taking to long to generates and the also want to show only one item for the variable product.

How to reproduce the problem

Some merchants has 2000 products but inlcuding variables they have like 10000

It would be nice to also have an option to send only parent products to feed although I am not sure if it's up to Pinterest ads rules. For many product types variations are just different sizes or have some other negligible difference.

BTW if you decide to provide such feature (send only one variation) please provide better filtering options than Product feed Pro plugin as they are rather limited.
