Are there any viable ways to create UCITS ETF equivalents to VTI, VEA and VWO?

As a Singaporean investor, I'm trying to be tax efficient and hold my ETF investments in UCITS ETFs but cant seem to find equivalent for a US Total Market, Developed Market ex US and Emerging Market ETF portfolio.
The closest I can find are perhaps VDPG+VEUA to equal VEA and VFEG to mirror VWO and none for US total market.
Would you any alternative recommendations or thoughts on these combinations?
