hi

assuming a have some dictionary variables defined in some group\_vars location:

level0:  
level1-a:

somevalue: aaa  
someothervalue: 111

level1-b:

somevalue: bbb

someothervalue: 222

level1-c:

somevalue: ccc

someothervalue: 333

Basically i would like to setup an ‘override’ vars file (lets take a host\_vars as an example) for the single entry so that:

level0:

level1-b:  
somevalue: abc #value to override

Is overriding a single value in a dictionary possible?

Thanks for any insight.
