ongoing driveline modifications

Just had my driveline shorten after the latest rear axle modification and now have changed to another shorter transfer case and was wondering if I need to find another longer driveshaft and go though the proces again with a machine shop or can I have some driveline shop just extend the current driveline to the correct length-Which would be the most cost-efficient way to approach the process-TIA

they retube it, but yeah, usually like $125ish
