I can only do this quickly but highlight one of your HTC001 blocks and type BEDIT
locate the TERM01 attribute and move it to the middle of the square. Note there are a lot of other attributes that look to be in the way but just ignore them.
While that attribute is still highlighted call up the properties palette. Modify the justification and height to suit. I am metric so you will have to find the best size yourself.
Close the block editor.
type ATTSYNC and click on the block you have just modified.
Having done all that I find electrical doesn't always let you keep modifications to blocks. You may find they have all reverted back to OOTB spec when you do a renumber. I never found out why.
