Dolphin replace/remove invalid chars in filename when copying to NTFS?

Hi,

I just wanted to copy a bunch of files containing various characters like '?' 
and ':' in their names to an NTFS drive with dolphin, and got lots of errors 
because of that names. Dolphin does not remove those characters (or offer to do 
so), the only option you have is abort.

Of course, one could do that in a shell using pattern replacement, but the 
average user, who is not familiar with those bash/aws/sed tricks, will prefer 
a more convenient way. So is there a way of doing that in Dolphin?

Thanks
