Issue with importing XML

Hi all. I've been having this weird issue with conforming XML files (either from FCPX or even Premiere Pro) and I'm not sure if I'm missing something. Basically the workflow is such;

1) offline editor provide a xml based on the edit ( media file linked to proxy files normally )

2) colorist grab the xml , grade and export the graded clip in proress 4444 but in separate folders (just to avoid same shot diff in out point issue ) 

3) online editor grabs the graded clips and conform using whichever software. 

In my situation, I'm the online editor and I worked my timeline on Premiere Pro ( somehow seems easy and fast for me to make simple changes ) and my composition on NukeX ( export shots that need to composite from premiere pro ) but the issue is I can never conform the XML from the offline editor in Premiere Pro. The common issue would be; 

1) media timecode / duration does not match ( works well if i did my steps below )

2) having to locate each folder of the graded files to link ( anyway around this ? )

3) speed ram ( this is the biggest headache of all time. most of the time i have to eye match the and if that don't work i'll most likely ask the offline editor to give me the keyframe timecode ) 

Hence, my workaround at the moment ( its redundant but somehow works for me and also speed up my time of conforming) is to import the XML in Resolve ( had to learn about resolve just to solve this issue) , link the graded clips to it and re-export back an XML so that when I import the new exported XML from resolve, it will automatically sync all files into premiere pro. 

Am i missing anything that I do not know of ?
