960 Sequencer Longer notes on a single stage

How do you make a longer note on a single stage of the 960, or is it not possible,
or do you have use the Timing on the B-column of the 961 or use the envelope?

I’m a bit stumped with this one!

depending on your intent:

you can use ‘3rd row control of timing’ to adjust sequence step period;

or, a 962 analog switch and a 961 to switch between two B-col delay settings.
