Update Net Force Component GDs in SSP

1. Want to confirm that the β highlighted above should actually be β_i? That's what it is in the generated version; can I update it to have the i subscript in the manual SRS?

2.

Should the description from GD8 be split between GD8 and GD7 instead of having the description for both of them grouped under GD8?

Yes to both 1 and 2. Thank you @niazim3.
