I don’t see why this isn’t already a feature – I think it would be great if we can the option to have a better chart with all the indicators we need when we open it, and not have to chose a template every time.
This futures it’s already there. Just set you template, save it and press paddlock next to them.
Unfortunately not available on the mobile app as yet, but thems the breaks i guess and im certainly not complaining, but would be handy for simpletons like me! 
Thanks! didn’t know about this
