Mashups naming - tabs browser name different than mashup name

[ZbigniewK]

We are obliged to use naming conventions, based on PTC proposals, so every mashup has to have name like [organisation].[projectname].[mashupname]_DS.
On the other hand, when I view final mashup as end-user, I see this name in browser as tabname. 

How can I declare tabname in browser different than mashup name, something more functional and less scaring for final user, like Efficiency reports?
To clarify, here is printscreen, with red what's standard for thingworx, and blue - for what I want to achieve.

If you use a Master then you can add 'Title' which will be shown on the browser Tab.

This is not available on a Mashup, so only on a Master.
