need help with managing variation of similar set analysis expression for maintainability, performance

Hi,

I've a set of set analysis expressions that are my main expressions. I've included one of them here. Then I've variation of main expression that I've to use in straight table either to perform a calculation or for another data point. I've included several expressions below. I've included several screen shots of charts where I'm using them to provide some reference.

I'm trying to get help/guidance to see if those can be leveraged using a single variable (Multiple variables ???) for maintainability and performance. The reason I say maintainability is because it is possible that business may change logic of main expression in future. At that time I want to avoid changing logic everywhere

Main Expression for which a variable is created.

Count({<[Field_DocStat]={'NR'}, [Field_IsDFDoc]={'No'}, [Field_SDT]-={'Val1', 'Val2'}>}[Field_CPDID])

I've variable (vNewRequest) created for above expression that I'm using in objects on multiple tabs for example

=If($(vNewRequest)>=1,$(vNewRequest),Null()) in Chart 1 (refer to screen shots)

Other Expressions where variations of Main Expression is use for different calculation or data point values

expression 2

=Today() - Max({<[Field_DocStat]={'NR'}, [Field_IsDFDoc]={'No'}, [Field_SDT]-={'Val1', 'Val2'},  [Field_CPDID]>}[ReqDate])

expression 3

='SF - ' & MaxString({<[Field_DocStat]={'NR'}, [Field_IsDFDoc]={'No'},[Field_SDT]-={'Val1', 'Val2'}, [Field_CPDocID]>}[Field_CPDID]) &
Chr(60) & 'URL' & Chr(62) & 'https://weburl' &
MaxString({<
[Field_DocStat]={'NR'}, [Field_IsDFDoc]={'No'},[Field_SDT]-={'Val1', 'Val2'}, [Field_CPDID]>}[Field_CPDocID])
& 'weburlparamstr'

expression 4

=If(IsNull(MaxString({<[Field_DocStat]={'NR'}, [Field_IsDFDoc]={'No'},[Field_SDT]-={'Val1', 'Val2'}, [Field_CPDID]>}[FNDocURL])),'',
'FN - ' & MaxString({<
[Field_DocStat]={'NR'}, [Field_IsDFDoc]={'No'},[Field_SDT]-={'Val1', 'Val2'}, [Field_CPDID]>}[FNDocURLLink]))
