Re-generate attribute combination after adding a new attribute

[Ehwaz]

Hi all,

I have a brand new 1.7 prestashop store, and before my store was running with 1.4.

My question is:

is there a way in the  version 1.7 to addonly (one or several) attributes, and re-generate all the combinations as simply as it was in version 1.4?

If you remember 1.4 version, if you want to add some attributes, you click on the generator button, then add the attributes you want to add, then click on generate, and yep the new combinations are all in order!

With 1.7 version, very different, I don't see how to do this... I only found how to delete all the combinations, and create everything again from the begining (meaning add ALL the attributes again). Which is very boring.

Is there a way I did not see?

Many thanks for your help.

Regards.
