Wondering whether it would be a good idea to ask for and communicate intentions and expectations early on when first dating. Perhaps even on or before the first date. For example, if I were mainly looking for a serious relationship to develop perhaps I should explain that early. Then if she were just wanting to have someone to hang out with and definitely is not interested in a committed relationship but just casual, recreational dating then at least I know that up front and we can then proceed with clear understanding.

Dating is a game
Great idea on paper, usually doesn't work in real life. One problem is that many people aren't honest, even with themselves, about what they want ahead of time, and many times one party will confess later "I never intended to get involved with him/her." Dating is a game, a dance that isn't always played with directness and pure honesty.
Others will not know what they want till after they get to know you. Some people may be open to different kinds of relationships depending on the person.

Maybe they'll just want a casual relationship with someone they find only physically attractive while hoping to meet that elusive "Soul Mate." Maybe they'll realize later they want more than they thought. Trying to pin someone down ahead of time is probably going to feel really awkward to her.
