Installed apps management with FSLogix, exsisting fxr files

LS,

We are new with using Nedio MSP version and we want to use the FSLogix Appmasking which Nerdio FSLogix rulesets, is there a way to import the already exsiting fxr files generated by rule editor from FSlogix. 

For example we want to hide MS Visio, the ruleset from fslogix beholds 190 rules, and this you have to do for every existing hostpool where you want to hide Visio.

Or is there an other way to make this less time consuming?

Regards, Michael
