I wish to submit a changelist with multiple filespecs, e.g. ...this... ...file.h ...theother.... Perforce won't let me. I could create a changelist from a file but I do want a chance to review the files and enter the comment. This is for a command-line solution.
You can create a pending changelist, then move all the files you want into that, before submitting it. Even from the command-line, although I find p4V easier to use for this functionality.
