Version Control tab - how to exclude several branches with custom filter? Regexp is broken

Hi, 
In Version Control tab there is Branch filter (Branch > Select...) 
I want to create filter which excludes  some branches from my main remote and all other remotes.  To do this I try to use regep with negative look-ahead like

(?!(remote1/)|(remote2)|(origin/somebranch)).*

but it does not work.  When I reopen input window I see that IDEA splitted my input by pipe "|" into several lines which actually broke regexp. Also it mix lines order (see sreenshot below)

When I try to exclude just one remote

(?!remote1/).*

it works perfectly. I.e. idea support both regexp in this window as same as regexp support negative look-ahead.

At the bottom there is a message "Select one or more values separated with | or new lines". So it seems IDEA force splitting by pipe. 
Question: Do we have option to disable such split or any other way to exclude list of branches?  

Note: option 'include only braches which you want to see' is not acceptable for me
