Bulk preference setting

Is there any way to set preferences for contacts in bulk?
For example, if I want to set text message frequency to 2/day for a list of contacts, I have to currently do it one at a time - a very time consuming method. If I could select all the contacts and set the preference, it would be very useful.
I did not see any such thing in the bulk action menu.
Is there any way to do this?

when you select the contacts there is an option when you click dropdown in table header it says Change Channels.

I think you can do what you are asking from there.
