Don't want to create empty parse when no value found

I want to parse a variable from an url that sometimes it’s followed by an “&” and sometimes by nothing, in OB1 I was creating two parse blocks with the same output variable name with ‘create empty’ box unchecked, but here in OB2 that box doesn’t exist, so the first output is always overwritten by the second.

Any Idea or Solution?

If else would satisfy the purpose

There will be lot of if statements so a complex config with lot of blocks, why not just adding the checkbox from OB1 ?
