At present we cannot place U-bolts or support locators on fittings, elbow and tees as a result in Isometric we need to add these supports manually and get it counted in the BOM. We need more options to create customized supports as primary and secondary.
Hi,
I have found this Wiki article which might be helpful.

But I agree that even above-mentioned process is also time consuming, and It'd be better to have this feature available for fittings just like pipes.
