"Pick up seed" and "plant seed" sequences for a group


After I sucessfully planted my first single seed, I would like to plant a already defined group of seed. I realize that I can do a single sequence for a group, but in this case I need to combine two sequences in a loop (pick up seed and plant seed).
I read that there might be various approaches, and I am curious what would be the most practicable?
Guessing, I can merge those two sequences into one and execute it as a subsequence - correct?
