Its easy and I'll explain it here for you.

Click on the settings tab in your wallet and then options, a box will pop up with some options now click on Display. You will see 2 options and the box you want to check is "Display coin control features (experts only)" once done click apply then okay. Now once you have done that and closed the pop up window click on "Send coins" tab in your wallet and you should see the Coin control features Click the "Inputs" tab and a window will pop up then you will see Tree mode and List mode. Select list mode and there you will have all your coins and now if you want to combine them all into 1 block you just check all the boxes and then click ok. Once done you'll see Amount fee etc... copy the amount and paste it into the amount box under Label then put in your 808 coin address and click send don't forget about the fee though and you should then have all your coins combined in 1 block.
