Channel Lists should focus to most recent channel or not at all until [Enter]

Maybe this could be a user-level setting rather than a global change, but I struggle with the channel views changing focus while I'm building a channel selection. 

Usually (with some exceptions) while building a channel selection when [+] or [Thru] is pressed, the active channel list focuses back to the first item.  This becomes very frustrating when scrolling down the list for reference.  I'm constantly typing a number then scrolling back to where I was.

Could we have a setting to just not change the view until [Enter] is pressed?

I would also accept focusing to the most recent channel number entered.

Thanks!
