CCA AUTO multiple vehicles shared use

Hi All, first year with Taxcycle. I never liked how Profile handled a self employed client with multiple vehicles that were shared use and different % of personal vs Business on each AUTO. If I use the auto worksheets for each vehicle it doesn’t handle Class 10 autos correctly with terminal Loss when trading. If I put the auto into a pool in the regular CCA assets area it handles this correctly in the pool, but it seems impossible to take CCA according to the different % usage of each auto for that year. I have one particular client that drives 80,000 km a year and loves to buy used vehicles on the cheaper side, so he has additions and dispositions every year, sometimes several. He is north so he seems to be a Deer magnate. How have others found the best way to deal with high frequency and multiple autos at the same time while keep terminal loss correct and usage for CCA correct?
