@Mind-Brain @Auran131 thanks you all trying to help me 
I was expecting that you could tap a check box somewhere and it solved. 
.
I have searched on the forum and seems there’s several people met the same problem and they all made a workaround.
if it needs extra work to do that, I’ll just give up to use it.
never mind,this is not the core feature in my project,not very important.
And I have moved on to work on other aspects of the project so I didn’t reply in time sorry.
still thank you again.
