Understanding Adobe (Tags) - SRI Creation Functionality

Context:

• We are currently in the process of deploying custom JavaScript code on some webpages via Adobe Tags
• We understand that every time each script changes, this prompts a new SHA-256 encrypted value (SRI) to be created and this value is required to be whitelisted in the 'script-src'
• Whitelisted SRI associated with script1
• Implementing a new script2

Issue:

• We have noticed that despite whitelisting the SRI associated with script1 and only making changes to script2, script1 is producing a new SHA value

It would be extremely helpful if anyone can point me towards any Adobe documentation to understand the following questions!

1. Is there an Adobe recommended approach to knowing the SRI ahead of pushing code to 'dev, staging or prod'.
2. Adobe Documentation regarding SRI creation (if any)
