That is precisely the problem I have with manufacturers families, 99.999999% of the information is unschedulable, and of practically no value. So if you are using them, you have to add your own parameters and populate them, the main problem with that is, when you pass it to the FM guys, those parameters don't meet their needs and then they have to add their own paramaters and populate those.
This will continue to be a never ending loop of modification until someone somewhere issues a standard set of parameters for all to use. There is of course Cobie, but have a close look and you'll find multiple parameters for the same thing, last I checked there was 3? different parameters for length and no doubt whatever one you chose, it would be the wrong one.
