No way to access key when iterating over certificate variables (and probably also other complex variables)

[chrischu]

In the documentation (https://octopus.com/docs/projects/variables/variable-substitutions#VariableSubstitutionSyntax-Iteratingoversetsofvalues) it is stated that I can access the key of an iteration by just using the iteration variable,
e.g. for

#{each variable in Variables}
Key=#{variable} 
#{/each}

with variables like this:

Variables[a] = 5
Variables[b] = 7

the output is

Key=a
Key=b

However, when iterating through complex variables (e.g. certificates) there seemingly is no way to access the key, .e.g.
when using the same code but with the following variables:

Variables[a] = (Certificate with ID Certificate-1)
Variables[b] = (Certificate with ID Certificate-2)

the output is

Key=Certificate-1
Key=Certificate-2

Is there any way to access the key ("a"/"b" in this example) when iterating over complex variables?

I've run into this multiple times, there is also a similar problem in the reverse direction:

Variables[a] = 5
Variables[b] = 7

#{each var in Variables}
Key=#{var}
Value=? // How to get value? There isn't a documented way
#{/each}

Variables[a].Value = 5
Variables[b].Value = 7

#{each var in Variables}
Key=#{var}
Value=#{var.Value} // This works, but its obviously a workaround
#{/each}
