Customize Control instance on Chrome app

PLEASE consider allowing the ability to use a customize app to set the control instance in Chrome devises.  We are a K-12 and it is next to impossible to get some of our kids to properly type in the control instance URL correctly for us to help them.  In our VMWare Horizon View app we are able to install a helper app that has the location of the connection server, could you please look at doing this for your app as well?
