Is it possible to use structs in the ULP coprocessor

[ESP_HengYC]

There is I found .struct expression https://sourceware.org/binutils/docs/as/Struct.html

.struct 0
field1:
.struct field1 + 4
field2:
.struct field2 + 4
field3:

So in ESP32 compatible with this feature？ Could I see an example here?
