Credit spread ETF?

Would like to go long credit spreads via an ETF, but can't identify one.

Credit futures unavailable at IBKR, and long IG bond ETF LQD vs short HY bond ETF HYG isn't capital efficient.

Aware of any IBKR tradeable instruments (futures, etf) tied to credit spread directly?

 

Can't you just short/long two different bond future contracts? Like legging into a spread.

 

Can't your mum leg her mouth into two different cocks?
