The table is made but how do you make the expression in the unloading time bar to select the correct node and thus unloading time. Enclosed with pictures are the table and the empty bar.

I have a question regarding the unloading time. I want my vehicle to have a different unloading time for every server it visits, the entities it carries do not differ from each other. I looked at adding expressions but that's easier for the entitity specifically, not so much the server. Is there an (easy) solution to this problem?
