Is it possible to set the number of repetitions of each sentence?

There are A, S and D on the shortcuts.
With the “S” shortcut the sentence is repeated. Sentence repetition is very important in foreign language learning.
I have to keep pressing the “S” key to learn a sentence. But after a while this becomes very tiring.

It would be very good to assign a number of repetitions to the “S” key.
For example, I want to repeat each sentence 10 times, or unlimited repetitions. It would be very useful.
Also the sentences are often not complete. I would also like to be able to set the start and end time of the sentence.

Finally, as a pro user I would like:

For example: It would be very useful for my foreign language learning to be able to repeat the part of the video between 05:00 and 05:45 for (x) number of times.

Thank you
