[Q] How to disable email synchro but keep contacts / calendar synchro enabled topic

Hi,

I'd like to have a button that would enable / disable GMAIL synchronization only. All other synchro I'd like to have always enabled.

Now in 4.4.4 I have button that enables / disables all synchro.

I know that I can edit account synchro and uncheck gmail synchro - I would prefer something more effective such simple button.

Do you guys now how can I achieve that?

I'm currently on 4.4.4, CM nightly, using xposed, rooted.

Thanks
