Evaluating multiple products with one survey

I would like to do the following with one survey (see attachment)
a) Person X should be able to provide information to product A (feature 1 – feature N). This information should be cacheable so that the person can continue the survey at a later time.
b) The same person should also be able the provide information to product B within the same survey. Likewise to product A, also here the person should be able to continue the survey at a later time.
c) Thus, the person should be able to switch between providing information for product A and for product B within one survey.
Is this possible with limesurvey? If yes, how?
Thank you very much for your support

Hi, you should not cross post so fast.
Two minutes ago you got my answer in the German section.

What you did nor mention here that you said: There are about 100 different products.
And as I said.
If the respondent selects the two products before, then there are only two groups of questions with the product name dynamically set and where you can use the index to switch between the products.
