Slot Plug weld symbols Depth of Weld

I am working in SolidWorks 2015 SP5 In the weld symbols i have noticed the slot weld symbol does not seem to have a way to add the Depth of Weld. I this function missing from the SolidWorks welding tool?

I have been working around this by adding text but this is causing issues sometimes when drafters revise the drawings since the weld symbol and text don't always move together.
