VT in a Roth IRA, can I max it out without fractional shares?

21M and I'm planning to dump $7,500 (maximum contributions) of VT in a Roth IRA. I really love Schwab interface, but I found out they don't allow fractional shares.

Is there any way for me to max out my contributions of VT in a Roth? If I buy the max amount I will still have leftover contribution space which I don't want.
