I have seen a few gizmos that relink your read nodes in nuke. I prefer to use a StickyNote, that way I don't have to rely on anything being installed if I switch to a new computer.
Create a StickyNote and in the name field type filepath . In the label field type your file path to your project mine is: volumes/SSD_Video/FISK/Fruitvale. My computer is a mac so I have volumes/. If you have a windows machine this could be D:
As a work flow I usually create a couple of StickyNotes and copy and paste the text from one to the main StickyNote. So I have my home computer which the label is work/work/ and I have my work computer /SSD_video/Fisk. When Im at home I paste the work/work/ in the main StickyNote and vise versa when I go to work I paste /SSD_video/Fisk.
Now all you need to do is and some text into each read node you bring in.
In the read node add [knob filepath.label]. This path is a continuation from the StickyNote so really your path is split in half. First half on the StickyNote then the read node picks up the other half. So [knob filepath.label] is taking the place of volumes/SSD_Video/FISK/Fruitvale and files it in from the StickyNote.
