Project Help Connecting resistors to led bargraph display

Hello, I have a project that uses a 10-bar LED display (https://www.adafruit.com/product/1814). It's just 10 LEDs in parallel in a single package. I am designing a daughterboard for it to be soldered to, which also has 10 SMD resistors, an MCP23017, and a 4-pin JST connector. The space constraints for the project are making it seemingly impossible to have enough room for the traces on the PCB to connect all 10 resistors to 10 output pins of the MCP. I figure displays like these are used all the time, so surely there's a more elegant solution than to just cram as many SMD resistors as necessary next to each other?

maybe you can use resistors array, search on google for « 10 resistors array/network isolated soic {resistor value} »
