Unhappy How to automatically update U-boot environment variables using uEnv.txt via TFTPBOOT?

I have a uEnv.txt file sitting on a TFTP server and whenever the zybo board downloads the file I have to manually input the "env import" command to update the variables from the recently downloaded file. Is there a way to automate this process within the uenv.txt file?

Command to tftpboot to download uEnv.txt:
tftp_boot = tftpboot uEnv.txt
bootcmd = run tftp_boot

Contents of uEnv.txt:
bootargs_config=setenv ipaddr; setenv serverip; setenv bootargs console=ttyPS0,115200
load_image=tftpboot ${netstart} ${serverip}:${boot_image}; bootm ${netstart}
uenvcmd=run ${load_image}
