Vertical conditional logic with a new variable creation

[SAS_nova]

I have a following sample dataset and looking to check iteratively for each ID if the combinations on Var2 (eg: CC85 & CC86) or (cc54 & CC57) are present. Each ID can have one or more (than 5) observations. If those combinations are present then create a new variable called 'combo' and assign values like 'Hcc801' and  'Hcc501' respectively.
No combo value for a single ID or if the conditions are not satisfied then the combo = 'NA'.

Please note, there are many other combinations along with CC85 & CC86 or CC54 & CC57 that need to be incorporated.

data t1;
input ID Var1 $ Var2 $ Rank;
datalines;
1 N179 CC135 2
2 I214 CC85 1
2 A419 CC86 1
2 A500 CC100 3
3 A100 CC54 1
3 A101 CC57
;
run;

Thank you in advance for your help!

Please show us the desired output table.

output should look like below:

ID	Var1	Var2	Rank	Combo
1	N179	CC135	2	NA
2	I214	CC85	1	HCC801
2	A419	CC86	1	HCC801
2	A500	CC100	3	NA
3	A100	CC54	1	HCC501
3	A101	CC57	2	HCC501

	 else 'NA'
end as Combo
 from t1
  group by id;

Thank you! I see those grouping makes the entire thing different!
