Import activty to watch

Hello!

I was out for a bikerun this morning and saved the activity mid activity and had to start a new activity, now i have two seperate activites on my watch and I really dont like that. I have combined the activites on my computer so thats it is 1 acitivity. Is it any way to import this to my watch so i can have the combined acitivty in my watch instead of the two separate? thanks
