Need an option of scroll bar in UV to review images by sliding the bar up and down in each series

Customer said they are looking for a viewport for a series and if want to view all the images in a series and instead of using a left mouse and go through the images.

They wanted to know if there is a option to add a scroll bar in UV to review images by sliding the bar up and down in each series.

Checked manuals/documents, the documents primarily discuss scrolling using the mouse wheel fast scrolling features and keyboard shortcuts for navigating through images.

Checked with GE seniors and consulted Alice. It seems like an special kind of enhancement request.
