Set Manager attribute in Active directory with accountid from different application

[NB]

We are having 2 separate applications for AD Regular Account and AD Service Account . When we create AD Service account , we want the manager field to be populate with accountid of ADRegular Account . Please let me know if its possible to pass a value from different application

{

"sAMAccountname": "${task.accountName}",

"displayName": "${accountname1}",

"Description" : "${description}",

"manager": accountid of ADRegular account ????? --> how do we acheieve this

"userprincipalname":   "${task.accountName}@xxx.com",

"objectclass":["top","person","organizationalPerson","user"]

I can think of below solution:

1. Store the account id  of all the accounts in some respective user's custom property using SAV to SAV

2. Pass below in the create account JSON of service account

"manager": "${manager.customproperty21}", 

where cp21 is the field where account id of manager is stored.

Thanks

Thank you . I had something similar in my mind too but we have used all our CPs for the user .Will look into this option anyways .
