We are an automotive wholesaler which means we deal with a lot of vehicles. One way to prevent typing errors for vehicle Makes and Models when creating a record is we created Parent and Child fields for Makes and Models.

So, if a user selects a Make, then the specific Models to that make are shown in the field. We have also created a Parent/Child field for Submodels, so when a selected Model is picked, then specific Submodels to that Model are shown. However; we have run into a limitation where Zoho CRM only allows 500 mapped Parent/Child relationships and from my understanding, Zoho has no intention of ever increasing that limitation.

I'm not sure what a workaround would be for such a case for the ever expanding car market of new cars coming out. Any help or suggestions are appreciated.
