Combat while riding horse

I have a project with ALS+DCS+HAP+RPGinv without any problems. I am trying to implement horse archery system as well. I couldn’t decide whether I should add the upper and lower body of the character by dividing it. or wtout horse archery system any suggest to riding combat…any advice?

Some sources say to use master pose component, but I don’t know how to proceed. grounded character can do all kinds of action. I have a rideable horse, but after riding I want to use the sword and bow in my grounded character.

sorry my english so bad…I hope I was able to express my problem.
