Equation symbols in Word

Hello. I've got a question about some symbols.

I want to put the "normal subgroup" Symbol, I mean, this symbol.

but I don't wanna open that menu and search for the symbol.

For example, many symbols can be written with a command, for example "less or equal than" may be inserted writting "\leq" in the equation. Or the ones at the left side of the "normal subgroup symbol", for "is subset or has this as a subset", can be inserted writting "\subseteq" or "\superseteq", "\cdot" can be used for "dot product"

This works a lot similar to LaTeX. the command for "less or equal than", and of "is subset of" is the same, the one for "has this as a subset" is "\supseteq", "\cdot" also works.

And I can write the normal subgroup symbol with the "\triangleleft" command in LaTeX. So... is there any way I can personalize this to have some command, or some quick way to write this symbol? The command \triangleleft doesn't work in word (Even when a lot of LaTeX commands work in word)...

It would be very good if I could assign it a command like the ones in LaTeX.
