How to load 2 Qvd's into one Qvd

[#1]

I am having a qvd which cossits of Jan to Nov data and  and other Qvd only Dec data

now by using this Qvd'S I should make one Qvd called Totalqvd

and also this process will be continued every month like in march again the Jan data will be added to the Totalqvd and this should happen automatically

how can we do it

and this monthly data we will be pulling from a specific path where the files are stored
