Generating TAD with ADDL dosing format

Hello, I was wondering if I could get some guidance from this great group. My issue is primarily with some diagnostic analysis, but this is taking me back to an old NONMEM problem. My aim is to run a VPC on a model I implemented, and if possible change the idv to TAD instead of TIME. The reason for that is the VPC graph based on TIME looks dreadful as the data is sparse and from different studies of different lengths. I'm having issues generating the TAD output column from my NONMEM run. I naively assumed I could easily do that, but looking at the NONMEM archives it seems this gets tricky when your dosing events are written using ADDL. Has anyone ever managed to find a solution for this? And if not, is there an alternative way to run the VCP on TAD, do we really need to get this column from NONMEM's output?
