Hello Tanveer Singh,
In the ribbon, go to Output > Document manager > Edit prototypes, this will give you a direct access to the "Prototypes" folder containing the prototype.
Open the prototype you want to modify.
Then "EXPLODE" the title block => all Advance Steel tokens are now visible
Then "PURGE" the HYPERSTEELPAGEHEADER block
Do your modifications (if you want to modify a token, select the token to be modified and display the "Properties" tab with the contextual menu ; then modify the "TAG" if you want to use another token)
Type "BLOCK" and recreate the HYPERSTEELPAGEHEADER block (in the "Block definition" dialog, select "Convert to a block")
Save & close the modified prototype
Regards
Philippe
