Is it possible to delete pretension sections defined in Simlab 2021.1

Hi All,

Is it possible to delete previously defined pretension sections defined in Simlab via the "Solid Pretension " tool in Bolt Modelling?

My abaqus input file accumulates previously defined sections and I have to manually delete them in an editor. 

Its seems when the pretension is defined, it does not appear anywhere in the "Structural Solution "tree. Any suggestions are welcome.
