Can you add a feature service layer that would appear in the map

[deleted-user-Xptbi2bLfMNa]

I understand the ability to add a custom base map through the creation of a Tile Package http://doc.arcgis.com/en/survey123/desktop/create-surveys/preparebasemaps.htm 

But what I am looking for is the ability to add a Feature Service (with assets and locations) so that it appears in the Base Map in Survey123 Connect ?

I have added the Feature Service in Connect and everything is there .....and appears in the Survey Form just fine
Is there a way that the FIELD crew can be able to see the existing Features in the MAP in the handheld view with Survey123 Connect as they Fill out their form?

The map displays all content by refreshing (INBOX) function on Survey submitted
