FIrst, weld symbols should be able to have another or multiple leaders attached to them. As of now, if you use the leader command, the size of the leader that comes in is not equal to tho one the weld symbol uses. Also welds that come in automatically need to be editable. What is the point of bringing in a weld from the model that cannot be changed in the detail? I end up deleting welds brought in because of macros because they are not consistent with common practice.
