IntelliJ code-fold/hide .map_err(|...| { ... }) ? ;?

In IntelliJ, is there anyway to code-fold or hide

.map_err(|...| { ... possibly multi line to dump helpful error msg ... })?

The thing is:

(1) source code wise, it makes sense to leave it in place
(2) when reading the normal path, it often ends up being clutter

If there way someway to have IntelliJ abbrev/hide it as [...] that expands on mouse over, that would be ideal.
