Can we use Sub and If statement the same as ANIMATED object?

At the ANIMATED object, we can use Elementary functions, Numeric functions,  and +-*/|, etc.
At the CSV route's $Sub and $If statement, we cannot use as these.
If we can use at the CSV route as the same as ANIMATED object, more useful.
Please consideration about this.

for example:

Code:

$Sub(1) = pluginState[175] / 10
$Sub(10) = pluginState[10] * 10 + 1

$If($Sub(1) <= 15)
.
.
.
$ElseIf(ABS($Sub(10)) <= 100)
.
.
.
$EndIf
