Add from Esri portal - Next page button

When using the Add from Esri portal command, the Choose Layers window only shows a subset of layer. For example, we have 165 items to show but there are only 50 listed on the page. There are no ways for user to scroll down or navigate to the rest of available layers, unless they use the search field. This comes with a risk of users don't find what they are looking for because it relies on tags. 

If VertiGIS can consider to add a navigator button, e.g. Next/Previous page buttons, down the bottom of the window, that will make a difference from user experience perspective. Thanks.
