Hey @sajarac,
I did some digging after Monkeyman's comment, and I was able to use Bot Framework Composer to set up the behavior you were looking for! I'll attach the diagrams of it below:


In short, you will want to set up a Bot Framework Composer Dialog like so, by asking the user a question in the same way you would within PVA, which is then followed up by a secondary question asking if they wish to repeat the question. If they say yes, the Repeat this dialog option will be called, allowing an instant retry of the question.
There is one very important step you must take with this layout, though. On both User Input (Choice) nodes, you must click on the Other tab, and set the Prompt Configuration titled "Always Prompt" to true, like so:

If you do not do this, the Bot will re-use the same responses it initially received for those questions, which will both not allow your user to find any other information, and will create an infinite loop that the Bot will fail out of.
Since you mentioned that you have not touched Bot Framework Composer at all yet, I'll also leave you some of the documentation for it below, to help you get started:

Hope that helps!
