[Mailman-Users] Mass Removal of Subscribers from Mailing List

[certuspersonality]

This is a new attempt to receive a meaningful reply to above subject.

I am not able to use Mailman commands on my server, as Mailman is 
integrated in cpanel of the hosting server I am subscribed to.
I need to remove all subscriber email addresses in a given mailing 
list to then mass-subscribe a number of new email addresses.
As the existing list is long and I do not have a backup of it on my 
computer, I cannot copy them into the field displayed for mass removal.
It is possible to mark all given entries in the 'unsub' column 
individually but that takes ages to do.
Is there a way of marking them in one go?
