Changing Array Formula

Hi All, looking to change this formula from an array to NOT array formula:
The purpose of the formula is to retrieve all values in $H on '2018CSV' in a list according to the $A$9 value. But since it's an array formula I cannot reorder the rows.

=IFERROR(INDEX('2018CSV'!$H$1:$H$100000,SMALL(INDEX(($A$9='2018CSV'!$A$1:$A$100000)*(MATCH(ROW('2018CSV'!$A$1:$A$100000), ROW('2018CSV'!$A$1:$A$100000)))+($A$9<>'2018CSV'!$A$1:$A$100000)*1048577,),ROWS('2018CSV'!$A$1:A1))), "-")

Any help would be awesome.

Thanks!

=IFERROR(INDEX('2018CSV'!$H$1:$H$100000,aggregate(15,6,ROW('2018CSV'!$A$1:$A$100000)/($A$9='2018CSV'!$A$1:$A$100000),ROWS($A$1:A1))),"-")

Thanks Dibbins, the helper column may be a good option in this case. Though I wish I could figure it out to lose the array.

Thx,

Thanks as well Tim. I think that formula is working, I will test it out- all well I will mark the thread solved.

Thx again guys,
