How to write this statement with another way best without re

Question

I work on SQL server 2012 i update two fields depend on every team id

update dpt
set Package=case when tmp.TeamId=1 then 1 end ,
PackageDate=case when tmp.TeamId=1 then getdate() end ,
Parametric=case when tmp.TeamId=2 then 2 end,
ParametricDate=case when tmp.TeamId=2 then getdate() end ,
Scribing=case when tmp.TeamId=3 then 3 end,
ScribingDate=case when tmp.TeamId=3 then getdate() end ,
Lifecycle=case when tmp.TeamId=4 then 4 end,
LifecycleDate=case when tmp.TeamId=4 then getdate() end
from PCN.DocumentPartTeams dpt inner join #Temp tmp on dpt.PartID=tmp.PartID and dpt.DocumentID=tmp.DocumentID
and tmp.Status is null

I need to rewrite statement with another way best as following

because i repeat same condition multi time

i need to write it one time only meaning as below

case when teamid=2

then date=getdata and parametric=2

so how to do that please ?
