Creating a scheduled task to sync phone's using PC...

Question

I have two NOKIA (bluetooth) Phones and want to create a scheduled task to synchronise their agenda to outlook without user involvment. Using PCSync2 and some batch file I can get the synchronisation to work.
One problem however remains. When both telephones are connected then a "phone selection" window appears. You have to manually choose which telephone to use. This makes the scheduled (automatic) task to wait for user involvment.
I have two questions:
1
are there any commandline parameters or registry settings to make clear which telephone to use during the next sync, and the selection window not to appear?
2
Are there any commandline parameters or registry settings to have PC Suite think that just one telephone is present (that the  second one is temporary inactive or switched off). Then again the selection window would not appear.

Answer 1

Here is a functioning task It can be easily edited in PowerShell or in notepad to alter the timing

I have edited and reloaded the XML many, many times.  It works very nicely.
¯\_(ツ)_/¯
