Custom Scale Input for Geocortex Site with Vector Tile Layers

Hi all, I recently added a Hosted Tile Vector service to my Geocortex Essentials Browser (4.15.3.0) and the custom scale input switched from being able to handle user-defined scale inputs to only allowing a preset number of scales (the same scales that the Vector Tile Layer was configured at.)

Is that a limitation of using Vector Tile Hosted Layers? I would like to return the ability for users to define specific scale inputs to the browser if possible, but I don't see any option to define user scale inputs in the Scale Input Box settings in Geocortex Essentials Manager.

Has anyone else experienced this? Any insight or support you can provide is welcome. Thank you
