Editing Profile After "Profile Complex by Elements" has been used

Is it possible to edit a profile after the "profile complex by elements" has been used? I have a proposed bike path profile that needs more PIs added to it. I want two line segments to replace 6 different lines. Is this possible without having to redo the whole profile? I haven't had much luck using the Append profile tool either. I tried using the modify tool-> delete vertices, but is there a better way to add segments or delete lines? Once it is complexed I have all sorts of issues editing it. Any suggestions?
