Calculating Avg at column level for total of Avg's

[LMSSAS]

Hello - I created a table and proc report, code below and image of table.   I calculated "AVG APPS RTS" by dividing "Total Contracted  / Ready To Sell" at the row level. how do I get the "AVG APPS RTS" at the column level so that in the total bar at the bottom of my table  it shows the "AVG APPS RTS" instead as a sum of the rows? 

proc sql; create table TOHFinal as
Select Distinct
a.AGENCYNAME,
b.AHIPNeeded format=comma10., 
c.ReadyToTrain format=comma10.,
d.ReadyToSell format=comma10.,
sum(b.AHIPNeeded,c.ReadyToTrain,d.ReadyToSell) as TotalContracted format=comma10.,
0 as '2022 Sales Goal'n,
a.'2022 Sales'n format=comma10.,
calculated TotalContracted/d.ReadyToSell as Avg_Apps_RTS format=comma10.2,
today() as Rundate Format=MMDDYYS10.
From Active_Count2 a
left join Count_AHIPNeeded_TOH b 
on a.TOH_AGENCY=b.TOH_AGENCY
left join Count_ReadyToTrain_TOH c 
on a.TOH_AGENCY=c.TOH_AGENCY
left join Count_ReadyToSell_TOH d 
on a.TOH_AGENCY=d.TOH_AGENCY
Where a.AGENCYNAME is not Null

quit;

For the columns you want a total average calculated add MEAN.  The default is SUM.

define varname / mean ;
