Variable expansion in strings

[michalfita]

At the moment to use content of one variable in string assigned to another variable I have to:

VARIABLE := "content"
SINGLE := 'single ' + VARIABLE
MULTI := """
    multi """ + VARIABLE + """
"""

@default:
    echo SINGLE {{SINGLE}}
    echo MULTI {{MULTI}}

what is more complex cases is very hard to read and non-trivial to write.

The output is:

$ just
SINGLE single content
MULTI multi content

I'd like to achieve the same with:

VARIABLE := "content"
SINGLE := "single {{VARIABLE}}"
MULTI := """
    multi {{VARIABLE}}
"""

@default:
    echo SINGLE {{SINGLE}}
    echo MULTI {{MULTI}}

but at the moment the output is:

just
SINGLE single {{VARIABLE}}
MULTI multi {{VARIABLE}}

Is this fixable?
