STEP files contain only geometry information, so all features information is lost by definition when exporting to STEP/IGES format and that's why it's often used to exchange data, so people get the geometry, but not the know-how of building the specified part

Feature recognition tool Robbie mentioned doesn't find features from original model but rather analyses geometry and tries to create Creo feature resembling that geometry like hole, extrude, round or chamfer.

If you want make edits to imported geometry I'd rather consider Flexible Modeling extension for Creo Parametric - it allows for easier modifications of geometry without features.

You can use 'Feature recognition', but I'm not a big fan of it. It doesn't work that well I think.

It doesn't find the features that were used to create the model, it just finds a shape, i.e. a hole, removes it, and creates a new feature making that hole on the same spot. Then you can modify it, dimensional or in positioning.

Sometimes this can be handy, but I prefer to keep clear from this messing about. If it's only a small change, like one hole that needs to be moved, I close it using an extrude, and make a new hole with an extrude or hole feature. If there is a lot to be changed, I usually remodel the whole part.
