Composite true positions in Legacy

I'm being required to use Legacy GDT reporting for a program.
I haven't used legacy before and need help on how to measure/report these composite true positions using it.

Datum A is a surface
Datum B is a bore
Datum C is a bore
I have my alignment set up to ABC.

In TP#1 how do I ignore C to get the AB alignment?
and how do I get just B for the composite?

In TP#2 How do I get the composite with no datums?

Can Legacy do MMC bonus or MMB datum shifts?

TP #1:

{"data-align":"none","data-size":"medium","data-tempid":"temp_22355_1648740249085_596"}

TP #2:

{"data-align":"none","data-size":"medium","data-tempid":"temp_22356_1648740215078_727"}

Cris_C could we build off your example?

I have a part similarly set up to the example you give. instead of -A-B-C- it is -A-B-Z-

Here is our FCF:

TP | DIAM 0.188 | A | B (M) | Z
TP | DIAM 0.020 | A | B |

Datum -Z- is a point taken at R7.1063 from -B- and 14.3 degrees from the center of the hole. I've included a (horrible) picture to illustrate. The rotation is from -B- to the indicated hole

How would this be done? We use legacy here too.

How would I get accurate TP for each (five in your example) hole for both callouts?
