[Tyriar]

Is your icon request related to a problem? Please describe.

microsoft/vscode#239356 is adding a new "Alias" kind for terminal suggest. Currently this is using the replace icon as it's a similar concept "a maps to b":

Describe the solution you'd like

Some icon distinct from replace that clearly means alias.

Since this is in an intellisense widget we could also consider color if it makes sense. Editor icon reference: https://code.visualstudio.com/docs/editor/intellisense#_types-of-completions
