Core, abdominal section

I was wondering if it is possible to add another category to all the heading.. others, standing, seated, twists etc… and add abdominal work / core?? so many yoga classes include core work now so this would be helpful to not only me but so many others.. at the moment I'm having to add my own and put it on the 'others' category but a specific 'Core' heading would be wonderful and very useful to me and many other students.. Yoga is evolving and changing so much.. more flowing.. more core and bandha work so It woould be great to see you're updated your product swell.. this would open it up to many more teachers.
