You create another wallet regardless.
File > New/Restore > Next > Standard Wallet > Next > I already have a seed > enter your seed
You can then send over those bitcoin to your main wallet.
I can have two different wallets in one electrum?
Yes, it will just ask for which wallet do you want to open anyhow, so you can have two wallet files on a single Electrum client.
Or you could do this instead if you don't want the hassle of having to access two different wallets:
File > New/restore > Standard Wallet > I already have a seed > Options (tick the box for BIP39) > Enter Seed > On the derivation path text box, change
44' to
49' > the rest is just a bunch of clicking next until you're done.
Your addresses and balance with appear once the wallet is done syncing, all on a single wallet file.
