Possible to set electrum-ltc to a specific receive address?

I'm not trying to do anything devious here although I can see how the capability could be misused. I was following some howto when I started that told me I should download and install Litecoin core if I wanted to mine, so I did. Got an address from it which I used as my payout address for litecoinpool.org, I'd made about $4 worth of Litecoin so I decided to take a payout since the price was spiking.

I didn't know that Litecoin core has to download the whole blockchain before it can receive a payment (apparently). My internet connection is a cell phone, that's totally impractical. I've read that unclaimed Bitcoin payments get returned to the sender after 30 days so I waited 30 days to see if I'd get it back, I didn't. So have I just made a donation to litecoinpool.org? Oh, well.

I've since got electrum-ltc set up (on a Pi, my old SD card crapped out) and rebuilt my wallet from my seed but that litecoin core is history. I've changed my payout address to my electrum-ltc.
