1) press D to change the cursor, until you get the area selection cursor
2) highlight all the A/B roll material in a partic interview, by dragging the cursor over it
3) change the cursor back to the normal arrow cursor, and drag that material to a new location. If you find that a bit iffy, first press ‘G’ to group it all, then moving it (whether ripple is on or not) will be as a single object
Could also cut/paste it, if you prefer
