Update context for custom field with scriptrunner

[arielei]

Hello Community,

I have custom fields that are set Globally.

I want to change them to specific projects.

i have an array of project keys that i want to run a script that will update the CF context.

for example, the array or project keys to set: [WHMKUK, WHH, WEBS]

is this possible via script runner in jira DC?
