How to replace Variables (auto set/replace Variable) to compare (Condition block) ?

[migen]

I see there are - Set "current market" for next blocks / Set "current timeline" for next blocks - to auto replace symbol and timeline in next blocks for comparing values with less codes.

My question : is there anyway to "Set Variable for next blocks" ?
Because I have 15 Variables (different values), it needs 15 group of blocks to compare them. While it just need 1 group of blocks with "auto set/replace Variable" to complete coding.

@migen there's many ways to set variables. You gotta give some example project so I can see what you mean

here is example project.
I have some EUR Conditions (day 1) then get result - Variable "EUR_1"
Same with day 2 ... day 15.

then, if
Variable EUR_1>0
...
Variable EUR_15>0

get result with Variable EUR.

My question : how to replace Variable EUR_1 with EUR_2... EUR_15 in Condition block EUR_1>0 ? So I just need 1 block without 15 blocks (for 15 days)
