Listing of keys for parametrized report variants in RStudio Connect

I have some questions related to the thread linked above:

(1) Is it possible to get a listing of the keys for the different report variants of a parametrized report?
(2) Is it possible to get a mapping from parameters to the key

The reply in the thread above suggested opening each variant to get the "vanity plus key" combination for a report variant:

The variant with ticker="MSFT" might have the URL /stocks/vhTapsdut/
...
You can find this "vanity plus key" path by visiting any of your variants and then using the "Open Solo" link in the RStudio Connect dashboard.

Is there a batch way to recover the keys if you have many variants.

Thanks
