I don’t believe there is, but I’ve often wanted/wondered about this. This probably isn’t an elegant workaround, and my guess is you’ve probably wound up doing this already, but:
For simple conditions like “IF X: command; command”, It’s not a big hit on character count to just write the if statement again on the following line. But this presumes the first commands don’t alter X. And this is maybe most applicable to if, as other conditional statements get longer.
If you had a line to spare you could have a longer condition which you assigned to X on the line before a conditional, and still keep the if condition short.
This would check that both TR 1 and TR 2 are currently high and then execute the following 2 lines of commands.
X AND TR 1 TR 2
IF X: commands
IF X: still more commands
With that being said, I would also be in favor of some sort of operator (or ideally maybe just a symbol, tho I bet they are scarce) which ties 2 or more lines to the condition on the 1st.
