I agree with the other QBO users on this thread that this functionality as designed is not working for us. 

I think the consensus is we would prefer to keep all other info the same if we change the product/service option.

Since we are only changing one single option - it is reasonable to expect that the program doesn't assume we want it to change other options.

I would like to officially add this as a 'feature request' to your software roadmap management team.

Is that possible @HoneyLynn_G ?

Thanks!
