Is it possible to compute angle between two rings in GROMACS?

GROMACS version: 2020.2
GROMACS modification: No
Is it possible to calculate the angles between rings in gromacs ( for example in oligosaccharides composed of glucopyranose rings etc)? If not in GROMACS, do you know other programs in which it could be done? Thank you in advance for your help.
Best regards
