Typing variable names directly in input fields

Is there a way to enter variable values manually by name directly into input fields, without selecting them from the panel? For instance, I have spacing values like 100 = 8px, 200 = 16px, 300 = 24px, and so on. I was wondering if there’s an option to type their names or values—like space-100 or 100=8—directly into the input fields and have them automatically filled with the corresponding values. Repeatedly choosing these values from the panel slows me down. I think allowing manual entry would speed up the workflow and improve precision, especially when reusing known token values.
