That's what cleats are made for. However on my Harken block the angle adjustment is to coarse to find a setting which works from the trapez and the trampoline, so I can't cleat going in.
I never cleat going out, as it is good to sheet in a bit tighter when going out. I have it in the forward hand, so I do not need change hands, when I am out. When going in, I let the sheet in the forward hand, grap the trap line with the sheet in the hand and go in. As Jalani explained, you have to stay longer out to not loose too much speed due to unsheeting when coming in. If your cleat can easily be used from the wire, you can cleat, head in the wind and go in. The boat turns faster when you are in and loose less speed. When changing sides, uncleat, let out a bit and go on the other side in the wire, sheeting in that way.
I wish I would have a block with finer adjustment. The Ronstan blocks seem to have also only a coarse adjustment...
