My "C" question was "Multi channle", no "Multiple times", what I mean is if I can select all my channels (included Google+ profile and Google+ pages) and share to all in one time. (Sorry for my English) Is it clear the question ?
As I understood, all happens greatfully Composer App. So, then would be good know if is possible select all my channels and save "these selection" group in my Composer App settings as "All my favorites channels", so each time I want to share I can select my "All my favorites channels" and quickly share. Is it possible ? Or have I to write and rewrite the message to share and each time can select only one channel ?
Only back-end social channels can be selected in the multi-channel selector.
Channels integrated via mobile social sharing require to re-share the message every time for each channel. By default, Composer editor initializes the field with content to ease the process, however, you could have to edit the post to finish the post styling. For example, Instagram only allows to send the image (not the post message).
