Bolt Spacing between anchors

Is there a way for me to use the program and be able to use a spacing of 4d (non torqued) instead of the 6d (torqued).

When I use the 4d spacing, of 3.25" for 7/8" bolts it does not let me run unless it's changed to 5.25" (6d) between bolts.

Your response is greatly appreciated.

Thanks,

John
