Importing combinations via CSV "Impact price" does not include option "Tax included"

[Aldeag]

I have Prestashop 1.7.7

Importing combinations via CSV "Impact price" does not include option "Tax included"

But if I import the price from Combinations, Impact in price appears but it does not indicate whether or not it includes the tax. And it does not.

I should be able to add an impact price with final price so "Tax included" is a must but I don´t have an option so I have to include a column in Excel and make an "inverse" Price without tax calculation formula before import.

One would expect such a including / excluding tax option with all product related prices.

Another option would be a must is: if I import quantities via combination csv I should have an option of setting the new quantities as the actual quantities or ADD the new quantities to the already existing quantities.

Thanks for your help in advance.
