Can you enable an Advance search in the Position Search when creating a Succession Plan?

Content

Greetings Folks! 

We are in the midst of testing 19B and enabling RUI. Does anyone know if you can enable an advance search in the 'Position Search' when creating a Succession Plan? 

Currently we only see roughly 20 values in the search results and can't see anything past that, which would require a user to search by  position ID instead of position name. 

This 'issue' seems specific to RUI, since it's a new page in 19B, but could be both. 

Any guidance on solutions would be greatly appreciated. 

Thank you, 

Heather Seely
