ADXL355 Pin Function Groups
Source: Analog Devices ADXL354/ADXL355 datasheet, Table 9. ADXL355 Pin Function Descriptions.
Each pin is assigned to exactly one functional group; no pin is duplicated across groups.

Table

Functional groupPinsRationale / datasheet function
Power supplies5 VDDIO, 8 V1P8DIG, 10 V1P8ANA, 11 VSUPPLYVDDIO is the digital interface supply; V1P8DIG and V1P8ANA are internal/external 1.8 V digital/analog supply pins requiring decoupling; VSUPPLY is the main supply input that can feed the internal LDO regulators.
Ground / return6 VSSIO, 9 VSSVSSIO is digital ground; VSS is analog ground.
Serial interface1 CS/SCL, 2 SCLK/VSSIO, 3 MOSI/SDA, 4 MISO/ASELThese pins implement SPI and/or I2C interface functions: chip select/I2C clock, SPI clock/I2C mode enable, SPI MOSI/I2C data, SPI MISO/I2C address select.
Interrupt / status outputs12 INT1, 13 INT2, 14 DRDYINT1 and INT2 are interrupt pins; DRDY is the data-ready output.
Reserved / optional tie7 RESERVEDDatasheet says this pin is reserved and can be connected to ground or left open.

Note on naming
For Flux grouping, I would avoid putting each ground in a separate functional group unless you specifically want separate symbol sections. Functionally, VSSIO and VSS are both ground/return pins, but they still keep distinct pin names and descriptions so the digital vs. analog return distinction is not lost.
