How to add description on each Image in Slider Widget?

It looks like adding a description for all uploaded images in the slider is not allowed. I tried to find a workaround for your requirements, but I was not able to.

If you would like I can submit your requirements as a feature request to our backend team for evaluation. However, please keep in mind that there's no assurance whether this will be implemented. It will highly depend on the viability of the feature, the number of similar requests we get, along with the workload of our Developers.

Looking forward to your response.
